That's not entirely true.

Productivity has raised so much in the past decades that where you used to need four or five people working and paying taxes to maintain one pension, now we just need one or two. If we truly had a problem here we could even tax smarter the productivity and get more money for retired people without affecting the workers.

Plus, who says retirement needs to be paid by wage taxes? Why not by other means like taxes to the rich?
